Hi,
I have been trying to get chan_ss7 to work for almost 2 weeks now. I
think I may be closed, but still I am stuck with some config issues.
Would someone please kindly help out?
Here is my software combination:
asterisk-1.4.21.2
zaptel-1.4.12
chan_ss7-1.0.95-beta
Here is my config:
zaptel.conf
span=1,1,0,ccs,hdb3,crc4
span=2,0,0,ccs,hdb3,crc4
#span1
bchan=1-31
#span2
bchan=32-62
